Introduction of transgenes wil result in

Options

A. Formation of a new species
B. Formation of a new protein
C. Alter a biosynthetic pathway
D. Both B and C

Answer

### Step-by-Step Solution:

1. **Understanding Transgenes**:
- A transgene is a gene that has been artificially introduced into the genome of another organism through genetic engineering. This process is known as transgenesis.

2. **Function of Genes**:
- Genes encode for proteins, which are essential for various physiological functions and biochemical reactions in living organisms. The introduction of a transgene can lead to the production of new proteins.

3. **Evaluating the Options**:
- **Option A: Formation of a new species**: This option is incorrect. The introduction of a single transgene does not result in the formation of a new species; it typically requires multiple genetic changes.
- **Option B: Formation of a new protein**: This option is correct. The transgene can encode for a new protein that was not previously present in the organism.
- **Option C: Alteration of a biosynthetic pathway**: This option is also correct. The new protein can influence existing biochemical pathways, potentially altering them.

4. **Conclusion**:
- Since both options B (formation of a new protein) and C (alteration of a biosynthetic pathway) are correct, the best answer is option D: both B and C.

### Final Answer:
The introduction of transgenes will result in both the formation of a new protein and alteration of a biosynthetic pathway.
